NGC 2366

NGC 2366 is a Magellanic barred irregular dwarf galaxy located in the constellation Camelopardalis.

There has been confusion about the various components of NGC 2366 and its neighbouring galaxy NGC 2363. At the southern end of NGC 2366 is the large, luminous HII region known as Markarian 71 (Mrk 71).

To the west of Mrk 71 is another dwarf galaxy NGC 2363 which is interacting with NGC 2366. Corwins' notes remarks that there are two galaxies with two NGC numbers clearly attached to each one. "We shall just have to get used to calling the HII region "Markarian 71" (or one of its other names) since it is not N2363 as we've thought all these years."

Within the region known as Mrk 71, there are two super star clusters (SSC) which are named 'A' and 'B' or 'Knot A' and 'Knot B'.

Other names for the above components include: NGC 2366-I, NGC 2366-II, NGC 2366-III, NGC2366-A, NGC 2366-B, NGC 2366-C, NGC 2363-A, NGC 2363-B.

NGC 2366 is an outlying member of the M81 Group.

NGC/Mrk71 is home to numerous young, gigantic blue stars, which in gas-rich star-forming regions, emit ultraviolet radiation that excites the hydrogen gas, making it glow. At a distance of approximately 10 million light years, it is close enough for astronomers to discern its individual stars.

Within Mrk 71 there are two super star clusters which will be referred to as Mrk 71 knot A (Knot A) and Mrk 71 knot B (Knot B).
